Answer:

8⁶/8⁻⁵
8¹¹

Step-by-step explanation:

When increasing the power of an integer by another power, you should multiply both powers to find the total power that the integer should be raised to. In this case therefore:

= 3 * 2

= 6

So the numerator will be 8⁶

When dividing the same integers raised to powers, you should subtract the power of the divisor from the power number being divided.

In this case therefore, you are to subtract (-5) from 6 (calculated in first part).

= 6 - (-5)

= 6 + 5

= 11

Another way of writing the above will therefore be: 8¹¹.

Write the set of points from −6−6 to 33 but excluding −2−2 and 33 as a union of intervals:

Softa [21]

In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .

For union, we use U.

For the points that we have to exclude , we put parenthesis on there side that is ().

Therefore the required interval form is

$[-6,-2)U(-2,3)$
